Title: Industrial vehicle
Inventor: MIHASHI MASATO
IPC: B66F9/075
Filed: 1999-12-09
Abstract: PROBLEM TO BE SOLVED: To easily prevent turnover of a forklift at low cost and reduce the labor required for maintenance work, etc. SOLUTION: A front wheel and a rear wheel are provided at the front and rear of a vehicle body. A front axle serving as the axle of the front wheel is fixed to the vehicle body. A rear axle serving as the axle of the rear wheel is supported by a center pivot in such a manner as to be capable of oscillating vertically relative to the vehicle body. A lock device comprises a lock plate provided on the rear axle, and a lock mechanism provided in the vehicle body for clamping the lock plate to lock the oscillation of the rear axle. When the vehicle travels straight, the rear axle is released from the state of being locked by the lock device to enable the vehicle to stably travel off-road.  At times other than when it travels straight, the rear axle is locked by the lock device to support the vehicle at four points at the front and rear wheels to prevent turnover of the vehicle body caused by inclination, etc.

Title: Liquid chemicals feeding tool
Inventor: YAMAMOTO MASAHIKO
IPC: A61M5/145
Filed: 1993-12-31
Abstract: PURPOSE:To make the tool low-priced, to simplify the structure, to make it suitably disposable and to satisfy all the conditions of satisfactory flow rate control performance by providing a driving part with the helical advancing mechanism of a gasket and a driving source with a spring take-up drum, spring winding reel and energized fixed load spring at a driving source. CONSTITUTION:When a fixed load spring 43 is wound around a spring take-up drum 41 by a winding-up means and released later in the state of assembling a liquid chemicals container part 10 and a driving part 30, the take-up drum 41 wound around a take-up reel 42 is rotated by a spring 43. This rotation is converted to the linear action of a gasket 12 by male and female screw members 32a and 32c of the helical advancing mechanism, the gasket 12 is advanced from the base part of a liquid chemicals container 11 to the head side, and liquid chemicals are pushed out. At such a time, since the rotational torque of the spring take-up drum 41 and the helical advancing mechanism is fixed and the flow rate is decided by the rotational torque, the change of the flow rate with the lapse of time is extremely reduced. On the other hand, since the liquid chemicals are fed through a pressure control valve, the feeding pressure of liquid chemicals is almost fixed, and a little liquid chemicals can be continuously fed for a long time.

Title: Air-conditioner and four-way valve with pressure regulating mechanism
Inventor: TAKANO YOSHIYUKI
IPC: F25B13/00
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To perform effective protection of a compressor during an overload of air- conditioning by a method wherein, in a refrigerant piping between a directional control valve to switch cooling and heating and a compressor, a bypass passage is arranged between the piping on the outlet side of the compressor and the piping on the inlet side of the compressor and the bypass passage is released according to the increase of a pressure of a refrigerant. SOLUTION: In an air-conditioner 1, a refrigerant cycle comprises a compressor 2, an indoor heat-exchanger 3, an expansion valve 3, and an outdoor heat-exchanger 5 and by switching a four-way valve 6, the indoor heat-exchanger 3 is functioned as a vaporizer during cooling operation and the indoor heat-exchanger 3 is functioned as a condenser during heating operation. In this case, a valve device 32 is located in the middle of a bypass passage part 31 located between passages parts 23 and 24 of the four-way valve 6. For example, when, during heating operation, air- conditioning is brought into an overload state and the pressure of a refrigerant is increased, a valve device 32 is gradually opened.  A part of a refrigerant the pressure of which is increased is caused to flow from a bypass passage part 31 to the compressor 2 through a pipe 11 and the increased pressure of the refrigerant is relaxed.

Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing semiconductor crystal by which a large-area GaN crystal can be manufactured and various problems caused by ELO growth using an ordinary mask layer can be avoided, and then, the manufacturing process of the GaN crystal can be simplified. SOLUTION: In the method of manufacturing semiconductor crystal, a substrate 1 having a recessed and projecting growing surface and carrying a mask 3 on the recessed surface 12 is used as shown in Fig. (a). When vapor phase growth is performed by using the substrate 1, crystal growth occurs only from the tops of the projecting sections 11 due to presence of the mask 3. As shown in Fig. (b), therefore, crystal units 20 occur on the tops of the projecting sections 11 when the crystal growth is started and, as the crystal growth continues, films horizontally grown from the tops of the projecting sections 11 are joined together and, finally, a semiconductor crystal 2 is grown so as to cover the recessed and projecting sections of the substrate 1 by leaving cavity sections 13 in the recessed sections as shown in Fig. (c).  Thereafter, the crystal 2 is separated from the substrate 1 at the cavity sections 13 as shown in Fig. (d).
